本文演示了测量表面活性切变粘液中球形粒子终端沉降速度的实验过程。准备了各种风湿特性的流体,并测量了平行壁之间无边界流体和流体中一系列粒子大小的沉降速度。

该程序的总体目标是测量不同学况的无界和有界表面活性剂基粘弹性流体中球形颗粒的末端沉降速度。这是通过制备不同浓度的基于表面活性剂的粘弹性流体来实现的,以获得广泛的实际逻辑特性。第二步是在直径为直径的烧杯中测量颗粒在无界流体中的沉降速度,在很宽的流体放射特性范围内,该烧杯比颗粒大得多。

接下来,在有机玻璃制成的平行板实验室中,在平行壁存在的情况下测量粒子的沉降速度。最后一步是测量液体的放射性特性。使用 ter,这些属性与粒子的沉降速度相关。
